With the D0 detector, we have investigated events produced in \bar {p}p collisions with large rapidity gaps and with jet production. We present the result of study at two center-of-mass energies, 630 GeV and 1800 GeV. The fractions of forward and central jet events associated with such rapidity gaps are measured and compared to predictions from Monte Carlo models with various structure functions of Pomeron. Hard diffractive events with production of intermediate vector bosons W, Z have been investigated.
